Abstract : The purpose of this report is to discuss the feasibility of emplacement construction through disturbed crater media produced by underground explosions. The primary use for these shafts will be for emplacement of nuclear explosives in order to extend a partially completed nuclear excavation or modify the geometry of an existing crater. A secondary usage will be to provide access for recovery of previously buried but undetonated devices. The area which is expected to provide the greatest potential for this type of emplacement will be civil works projects where nuclear explosions are used as a construction tool. (Author)
